“You almost tempt me to accept,” he said. “But it cannot be. If Miss Holm were not with us—well, I should be very boorish to refuse. But as a matter of fact I promised Miss Girton to join them in a sandwich and a glass of ale towards midnight, and I can’t let them down.” “Miss Holm will make your excuses,” urged Bittle, but the Saint shook his head regretfully. “Another time.” Bittle moved again in the chair, and went on with his cigar. And it began to dawn upon the Saint that, much as he was enjoying the sociable round of parlour sports, the game was becoming a trifle too one-sided. There was also the matter of Patricia, who was rather a handicap. He found that he was still holding her hand, and was reluctant to make any drastic change in the circumstances, but business was business. With a sigh the Saint hitched himself off the wall which he had found such a convenient prop, released the hand with a final squeeze, and began to saunter round the room, humming light-heartedly under his breath and inspecting the general fixtures and fittings with a politely admiring eye. “This room is under observation from two points,” Bittle informed him as a tactful precaution. “Pity we haven’t got a camera—the scene’d shoot fine for a shocker,” was the Saint’s only criticism. And Simon went on with his tour of the room. He had taken Bittle’s warning with the utmost nonchalance, but its reactions on the problem in hand and his own tentative solution were even then being balanced up in his mind. Bittle, meanwhile, smoked away with a large languidness which indicated his complete satisfaction with the entertainment provided and a sublime disregard for the time spent on digesting it. Which was all that the Saint could have asked. In its way, it was a classical performance. Anyone with any experience of such things, entering the room, would have sensed at once that both men were past masters. Nothing could have been calmer than their appearance, nothing more polished than their dispassionate exchange of backchat. The Saint worked his unhurried way round the room. Now he stopped to examine a Benares bowl, now an etching, now a fine old piece of furniture. The patina on a Greek vase held him enthralled for half a minute: then he was absorbed in the workmanship of a Sheraton whatnot. In fact, an impartial observer would have gathered that the Saint had no other interest in life than the study of various antiques, and that he was thoroughly enjoying a free invitation to take his time over a minute scrutiny of his host’s treasures. And all the while the Saint’s eyes, masked now by lazily drooping lids, were taking in all the details of the furnishing to which he did not devote any ostentatious attention, and searching every inch of the walls for the spyholes of which Bittle had spoken.
